Also seeing this with a APC Back-UPS Pro and usbhid-ups, but on a
physical machine, so no vmware shenenigans to mess with the USB
descriptors. lsusb shows the iManufacturer and iProduct:
Bus 005 Device 013: ID 051d:0002 American Power Conversion Uninterruptible
Power Supply
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x051d American Power Conversion
idProduct 0x0002 Uninterruptible Power Supply
bcdDevice 0.90
iManufacturer 1 American Power Conversion
iProduct 2 Back-UPS BR 900GI FW:879.L3 .I USB FW:L3
iSerial 3 3B1125X03827
bNumConfigurations 1
But usbhid-ups lists them as unknown before segfaulting:

Confirm that patching nut-2.7.2 with the patch in #5 fixes this:

0.299373 device->Product is NULL so it is not possible to determine
whether to activate max_report_size workaround
0.299390 Device matches
Although it seems that this is slightly random; trying again a second
time it actually sees the idProduct this time:
